by changing the polarity of capacitor of single phase ceiling fan can we change the direction of rotation from anticlockwise to clockwise
A: practically all capacitors will have an indication of polarity, it maybe a bar or sign or even a color code to signify the potential polarity to be applied to that terminal. There are however non polarized capacitors that will allow either polarity to be applied to either terminal
It will rotate faster.Since the fan is not designed for this, it will progressively ruin it.
yes
There are a variety of capacitor sizes in ceiling fans. The capacitor is dependant upon the characteristics of the fans motor. Whether it is a single speed, two speed or three speed. If you think it is the capacitor at fault for the fan not operating, take the fan down and open it up. This will give you the exact sizing for your fan.See sources and related links below.

Be certain to observe the exact same polarity as the old one. A capacitor does have plus and minus leads. Should an old defective ceiling fan transformer be replaced by a capacitor?
(1)What happens when polarity of the fan is reversed? It depends upon your definitions of reversal of capacitor,in a series circuit reversing a capacitor in the actual sense means not a mechanical reversal by changing its metal leads,its just reversing the current direction in the capacitor. (2)Now next question is does fan capacitor have a polarity? Ofcourse it has,all capacitors have polarity,but fans capacitor is not electrolytic capacitor,so it doesnt have inbuilt polarity. (3)How we recognize the polarity of capacitor of a ceiling fan? Since it doesnt have inbulid polarity,the direction of the current entering the mesh determines positive polarity and current leaving is assumed as negative polarity.while doing mathematical analysis we can take any convention it will not affects the magnitude since we are taking modulus in calculations. (4)Final Assumption reveling the facts about fans reverse rotation If we connect the fan in such a way that currrent is leaving or reversing the direction of current,the capacitor polarity changes and fan will rotate in reverse(since it is a single phase induction motor{note: rotating magnetic field and working of fan}),need of the capacitor is it gives the initial torque and technically improves the power factor,capacitor charges and discharges with respect to the frequency of the ac and gives the stability to the system,its efficiency will be lower and speed reduces if we remove the capacitor theoratically,so finally you can say the fan rotates reverse if we change the polarity of the capacitor(indirect meaning of changing direction of current).if you want any simple mathematical analysis of the detailed explanation,mail me at "ellipsis047@gmail.com" or call me 07259434969 "Sreenath SM(India)".i can make you understand the basis of all analog and electrical circuits.
The Capacitor with running winding is connected in parallel with main winding.

To change the ceiling fan capacitor, first turn off the power to the fan. Remove the fan blades and housing to access the capacitor. Disconnect the wires from the old capacitor and remove it. Install the new capacitor in its place and reconnect the wires. Reassemble the fan and turn the power back on to test the new capacitor.
To replace a capacitor in a ceiling fan, first turn off the power to the fan. Remove the fan blades and housing to access the capacitor. Disconnect the wires from the old capacitor and take note of their placement. Install the new capacitor in the same position and reconnect the wires. Reassemble the fan and turn the power back on to test the new capacitor.
Motor used in Table Fan is Split phase Motor(Continuous Running with Capacitor).It has Two winding Running coil + Starting Coil. Running coil connected Direct to Supply Starting coil Connected is series with capacitor than parallel with power.
To perform a Hunter fan capacitor replacement, first turn off the power to the fan. Remove the fan blades and housing to access the capacitor. Disconnect the wires from the old capacitor and remove it. Install the new capacitor in its place and reconnect the wires. Reassemble the fan and turn the power back on to test the fan.
To replace a ceiling fan capacitor, first turn off the power to the fan. Remove the fan blades and housing to access the capacitor. Take note of the wires connected to the old capacitor and their positions. Disconnect the wires and remove the old capacitor. Install the new capacitor in the same position and reconnect the wires. Reassemble the fan and turn the power back on to test the new capacitor.
To perform a ceiling fan capacitor replacement, first turn off the power to the fan. Remove the fan blades and housing to access the capacitor. Take note of the wiring connections, then disconnect and remove the old capacitor. Install the new capacitor in the same way, reconnect the wiring, and reassemble the fan. Test the fan to ensure it is working properly before turning the power back on.
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
